Capsule Sinkers
Although the USP does not specify the dimensions of sinkers allowing different sinkers to be used, it does have a diagram showing a suitable sinker device. This is the CERTBSK-JP. We guarantee this sinker will meet the specification.
Other documents may refer to other sinkers. For example the monograph for Amantadine Hydrochloride capsules (Pharmacopeial Forum Vol. 35(3) specifies CAPWHT-2S.
